Overview

Alloys with a copper minimum of the 50% and main zinc addition . Usually have zinc contents among 5 and 46% and until!! 3% of lead to enhance their/its/your/his mechanization by take-off of shaving. They can also to carry other elements as aluminium, tin, silicon, iron or manganese to obtain special properties.
